Electrical parameters for determining cable cross-sections
the battery current values and cable
cross-sections have been determined
for a battery at the end of a charge
cycle;
the current values and cable sections
for Mains 2 and load are given for full
rated load with a power factor of 0.8.

(1) the rated Mains 1 currents (In) have been
determined for a minimum float charging voltage of
423V and full rated load with a power factor of 0.8.
(2) the cable cross-sections are given for copper
conductors. They are calculated according to
permissible temperature rise and allow for line
voltage drops over a maximum length of 100 m
(AC circuits) or 25 m (DC circuits if cables not
provided). For greater lengths, the cross-sections
should be chosen to limit voltage drops to 3% (AC)
or 1% (DC).
this table has been drawn up for
rated phase-to-phase Mains and load
voltages of 415V. For voltages of 380V,
multiply the currents for Mains 2 and
load by 1.09; for voltages of 400V, use
the table in another language version of
this manual;
the current values and cable cross-
sections for Mains 1 are given for full
rated load with a power factor of 0.8
and a battery consuming its minimum
float charging voltage;
For frequency converters, the
parameters concerning Mains 2 are not
applicable.
The load parameters common to all the
converters are given in the table below.
For a parallel UPS, the parameters for
Mains 2 and load are also provided in
the table below.
For a modular UPS, the parameters
for Mains 2 and load are also
provided in the table below.

(1) the indicated heat losses are those produced
by the unit at full rated load and with the battery
float charging. They must be taken into account
when dimensioning the air conditioning system.
The cubicles are cooled by forced ventilation.
The air enters via the doors and grids at the bottom
and is discharged via the roof.
